![]() I don't know how to upload image here. The cost to this item:metal laser cut: 300rmb, stepper with gear box:150*3=450 ramp and 2560 about 150 all is RMB the stepper with gearbox, ratio is 5.18, original maybe is 10, can't buy in the market. and the precicion now is badly,some place will be improved. I test MAX'S example-driver, it worked well. Mpu6050 is not placed on it ,just on the way. I will test it and post some details here. |

Looks as a dobot to me  How are the joints on levers behaving? On Dobot they are designed very badly, one should not do that, ever. Better make them like this ecoursesonline.iasri.res.in/pluginfile.php/131477/mod_page/content/8/L%208%20fig.8.1(a).jpg only with a bearing. That would prevent any backlash in that joint. Although the main joints on dobot don't seem to be loose, they still don,t have a bearing. If you want to make it work longer you better redesign them to include couple of bearings. |

I am testing the mpu6050, on the other arduino UNO
and returned the follow data
int16_t ax, ay, az;
int16_t gx, gy, gz;
a/g: 5224 2424 13000 -293 -232 -91
a/g: 5324 2484 13040 -308 -449 -138
on the board labled the x and y, is the Y direction fixed on the arm?

Can we please not throw all the questions and discussions in one thread? Thanks.
When you create a new thread with this question please describe what arduino uno has to do with open-dobot. Also, I don't get the question, could you please rephrase it? The whole GY-521 board is fixed on a link.
